Example Embodiment

[0018] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0019] A double-mold flip casting machine for casting pistons, its structure is as follows figure 1 Shown. It includes a frame 1, on which a workbench and a manipulator are arranged, and an outer mold mechanism, a center core mechanism and a top mold mechanism are arranged on the workbench.

[0020] The workbench 4 is a rectangular flat structure, and the center of the workbench is provided with a through hole for placing the mold. The workbench is movably set on the center bracket 15 of the frame through the rotating shafts 14 located on both sides of the through hole. A turning oil cylinder 12 is arranged under one end of the workbench. The piston rod of the turning oil cylinder is connected with the bottom surface of the workbench for making The worktable rotates around the rotating shaft under the lifting operation of the turning oil cylinder. In...

Abstract

The invention discloses a double-mould turnover casting machine for casting a piston, and the machine comprises a rack and a workbench, wherein a through hole is arranged at the centre of the workbench, the workbench is arranged on the central support of the rack via a rotary shaft, and a turnover oil cylinder is arranged below one end of the workbench; an external mould mechanism is arranged on the workbench, a central core mechanism is arranged below the workbench, and a top mould mechanism is arranged above the workbench; and a manipulator and an electric control device are further arranged on the rack. The double-mould turnover casting machine disclosed by the invention is reasonable in structure, small in floor area, low in cost, simple and convenient in operation, fast in replacement for fixtures and moulds, stable in running, convenient in maintenance, low in fault rate, and high in the yield of the cast piston; and the double-mould turnover casting machine has the advantages of being small in floor area, high in production efficiency, stable in process parameter, stable in product quality and the like compared with a single-working-position casting machine.

Description

technical field [0001] The invention relates to casting special equipment, in particular to a casting machine for casting piston blanks. Background technique [0002] The working environment of the foundry industry is relatively harsh, and the degree of automation is also at a low level. Especially, the working environment temperature of the workshop for casting pistons can be as high as 40°C, and the labor intensity is extremely high. When producing engine pistons, most of them use the mold casting process to produce blanks. First, the mold for casting pistons is placed on the casting machine, and then the casting operation is carried out. The mold used for casting the piston includes a top mold, a lower drawing mold, a left outer mold and a right outer mold, and the left outer mold and the right outer mold are symmetrically arranged to form the outer circle of the piston after being closed. Casting machines can be divided into single-mode casting machines and multi-mode ...
